Application filed December 19, 13x37,` Serial No.'.55,302. (No model.)

To all whom it may concern.' A

-Be it known that I, JAMES .L LOWDEN, a citizen ofthe United States, residing at Boston, in the county of Suffolk and State of Massach usetts, have invented a new and usefulIniprovement in Separators, .of which the following is a specification.

The :object of my invention is to produce a separator for eiitracting grease, gri t,an`d water from exhaust-steam as it passes from the engine through the exhaust-pipe, and in which the products of condensation-#grease and grit are automatically carried ofi' by a` drip-pipe;

and the invention consists in certaindetails of construction, as hfreinafter fully described,

,and set forth in the claims.

detached. Fig. 4 is a view of the bottom perfoi-ated plate detached.

A represents the body of the separator, and

B a receiver for the grease, grit, and water that are separated from theexhaust-steam. The

vbody A is provided with4 suitablel flanges to. l connect it tothe exhaust-pipe C, as shown.

In the bodyA are secured'a series of plates, D D. These plates areprovided with a number of small holes, d d, around each of which, on the side nearest the engine, is a small lip or -ilange, e. Thev holes lin one plate are so arranged as not to come opposite the holes in the next plate, thereby preventing any steam from passing through without 'first coming into contactwith one or more of the plates. The cornbined area of the small holes in each plate must notbe less than the area of the exhaust-pipe', Aand I prefer to make it somewhat greater, so

'as not to impede the passage of the steam.

The plates are capable of being adj usted nearer' to or farther from each other, so as to regulate the expansion 4of the exhaust-'steam passing through and between them, the space between the plates being regulated by short pieces of' pipe f f,placed upon the boltsg, that secure the plates together. The central plate is proyided at the top'andon each'side with a boss oren- 5o p B', at its 4lower end. Near the upper end vof 55 the receiver is provided a perforated plate, Il, which rests upon a small ledge, k, formed in the'- receiver. The object fof this plate is to prevent the steam passing into the receiver 1n avolume. p y 'Q' ,F is a hollow float or ball connected by a* hollowstem,G, to a puppet-valve, H,provided with a hole through its center, so that the products' ofV condensation in the float will be carried off, thereby preventing'the float frombursting. The seat I of the valve is formed of leather or other suitable material, which rests upon a bushing, J, in which thelower part ofthe valve works. To the upper part of the tloatF is secured 'a short rod, K, thathas a bearing in a boss formed on the perforated plate E, so as to guide the valve when the iioat rises or falls. y

By having the seatI of the-valve H of leather the valve will not be injured nor prevented from closing should any grit lodge upon the `-75 seat.

To Vthe cap or cover B is secured a drippipe, L. On' one orboth sides of the receiver B is secured a sight-glass, M, so that the float and the content-s of the receiver'. can be seen when desired. Y

The exhaust-steam, passing in Vthe direction `of the arro'ws,comes into contact with the first `into contact with the plates causes any grease,l z

grit,"or water that may be in the stearl'-, to become -deposited upon the face of the plates, go

which deposits then run down the-plates and through the perforated plate E into the receiver B, the said deposits being prevented from running through the holes dby reason of the iianges e. -When the' receiverbecomes95 sufficiently full, the iioat F rises, opeuinglthe valve H, thus allowing the contents lof the -receiverB to escape into the drip-pipe L until forated plates, and a'. receiver provided with an sufficient ofthe Huid has escaped, when the valve again Closes, thereby preventing all escape of steam.

Should the plates D become damaged or worn out, they can be readily removed, so that a new one or set can be inserted by simply re moving the receiver B and takingout the Screw 7L.

l. A grease, grit, and water separator, eonsisting oi' a body provided with removable perautomatic discharge-valve, substantially as set forth.

2. The body A, provided with perforated plates D, in combination with the receiver B, provided with :L valve, I-I, operated by a float, substantial] y as set forth.

3. The body A, perforated plates D, pipes f, bolts g, and screws h, in combination with zo the receiver B and cover B', the perforated plate E,valve H, rod G, and float F, substantially as and for the purposes set forth.

In testimony whereof I have signed my name to this specification in the presence of two sub- 2 scribing witnesses.
